To all whom it may concern:

Be it known that I, FRANCIS M. BANGS, a citizen of the United States,residing at Deep River, in the county of Middlesex and State ofConnecticut, have invented an Improvement in Molds for Ingots, &c., ofwhich the following is a specification.

My present invention relates to a mold for casting ingots, although aswill be understood, it is not limited to this purpose, as the featuresto which the invention more particularly relates may be employed in anytwo part mold for any purpose. Heretofore in casting operations therehas been more or less difficulty experienced in both connecting theparts of the mold and disconnecting the same, necessitating theexpenditure of considerable time and labor in both operations. Theobject of my invention is to overcome these difficulties by theemployment of devices which are so associated with the parts of the moldas to be readily connected and disconnected thereto and therefrom, andwhen connected thereto to force and hold the parts of the mold togetherduring the molding operation. To this end in carrying out my invention Ipref erably employ one mold part with a series of spaced lugs, and theother mold part with a corresponding series of similarly placed bossestogether with a plurality of, clamping devices each of which at one endis adapted to be disconnectedly secured to the lugs on one mold part,and at the other is fitted With a pivoted lever adapted by turning thesame to engage the corresponding boss on the other mold part to forceand hold the parts of the mold in position for the casting operation aswill be hereinafter more particularly described;

In the drawing; Figure 1 is a plan view of the back of the mold; Fig. 2is an edge elevation of the same; Fig. 3 is an edge elevation of thefront part of the mold; Fig. 4 is a plan view of that part of the moldshown in Fig. 3; Fig. 5 is an edge elevation of the parts of the moldconnected for use; Fig. 6 is an end elevation of the part of the moldshown in Figs. 1 and 2; Fig. 7 is an end elevation of the part of themold shown i in Figs. 3 and 4; Fig. 8 is a cross section taken on line8-8 Fig. 5; Fig. 9 is a side elevation of a modified form of theinvention; Fig. 10 is a rear elevation of the container employed in theform shown in Fig. 9; Fig. 11 is an end view of the parts shown in Fig.9; Fig. 12 is an elevation of the lower end of the back of the mold asshown in Figs. 9 and 11, and Fig. 13 is a front elevation of the hingedmember as shown in Fig. 9.

Referring to the drawing it will be seen that in carrying out thisinvention the mold as illustrated is preferably made in two parts, theback part being indicated at 10 and the front at 11. These mold partswhen united are adapted to receive the metal to be cast into ingots,although as may be understood, they may also be fitted with a suitableframe and core for casting any desired article of metal At one end theback mold part 10 is fitted with a foot 12 having on opposite sidesthereof the extensions and lugs 13 and 14:, with the lugs 13 and 1%provided with bores indicated at 15 and 16 respectively. On thecorresponding end of the front mold part 11 there is a lug 17 which isprovided with a bore 18. The lug 17 is adapted to fit between the lugs13 and 14: and a pin or rod 19 passed through the bores 15, 16, and 18,so as to pivotally connect the parts of the mold together, the foot 12providing a convenient means for stand: ing the mold in an uprightposition during the pouring operation.

In suitable positions on the outer side thereof and adjacent the edgesthe back ,mold member 10 is provided with lugs 20 and 21 in oppositelydisposed pairs. Each of these pairs of lugs is provided with a recessextending through which is a pin 22 while the corresponding lug on theother side is provided with a similar recess extending through which isa pin 23. The front mold member 11 in positions correponding to thepositions of the lugs 20 and 21, is provided on its outer face withbosses 24 and 25.

In order to hold the mold parts together during the pouring operation Iemploy together with the hereinbefore described members of the mold, aplurality of clamps each comprising a body or spanner portion 26 adaptedto extend over the edge of the mold members when placed together and ahook 27 at one end, each hook 27 being provided with a recess 28, and apair of lugs 29 at'the opposite end. Between each pair of lugs 29 alever 30 is pivotally connected as indicated at 31 and each lever 30fitted with an eccentric '32.

From the foregoing descriptionit will be apparent that after the moldparts have bee pivoted together at the base or foot end thereof andplaced and adjusted to position, the clamps may be applied by insertingthe hook end 2? between a pair of lugs or 21. with the recess 28 in thehook end engaging the corresponding pin 22 or The body of the clamp isthen returned to co:- tend over the edge of the members of the mold andthe lugs 29 in each clamp passed over the corresponding bosses 2% and onthe outer face of the front mold member. Then by swinging the lei'ers 30from the full line to the dotted line position as indicated in Fig. 8,the eccentrics will be caused to engage the faces of the bosses '2 and25 to force the mold members together and hold the same in position forthe molding operation. Obviously the parts of the mold may be as readilydisconnected by reversing the hereinbefore described operation after theingot or other article has been cast. Obviously the abutting edges ofthe mold members may be offset as indicated at 33 or otherwise made tofit each other in such a Way as to make a tight joint.

In some forms of Work Where the mold is subjected to unusualtemperatures it may be advisable to employ container and a separate backmember of the mold in order to obviate the necessity of course ofsubstituting an entirely new back member when this part because ofcracking or otherwise, becomes unfit for use. The container is aseparate and tinished part of the mold structure and is adapted toreceive the back mold member which latter is subjected to the excessivetemperatures and strains in casting and when cracked or otherwise madeuseless may be discarded and another one used in its place. in this formof the invention as shown in Figs. 9 to 13 inclusive, the containermember indicated at l is preferably made in channel iron form. Atsuitable places the Webs or edges of the channel are recessed asindicated at 35 and spanning these recesses and placed on the innersides of the Web suitably secured thereto there are staple bars 36. Alsoin this form of the invention a separate hinge plate 3"!" may besuitably connected to the container at the bottom thereof. This hingeplate is provided with bosses in which there a bore 39 so that thecontainer may be hinged to the front member of the mold in a mannersimilar to that hereinbefore described in the other form of theinvention. in the back of the hinge plate there are recesses 40 oneither side of a central lug l0. ihe hack member of the mold isindicated i1 and at its lower end is provided with projections 42adapted tovi'it within the recesses ll) in the hinge member 3'? therebeing a recess t2 between the projections 4-2 to receive the lug so. Atits upper end and on its rear face the back member is provided with arib 43 having a projection or hook d4: adapted to extend over the upperedge of the container member between the WGbS or flanges thereof and tolie against the rear face of the con tainer. This rib together with theprojections secure the back member of the mold in that position on thecontainer member in which it registers with the front member of the moldwhen swung on the hinge to position against the back member for thecasting o 'ieration. The clamps are of the same construction as thosehereinbefore' described in conjunction with the form of the inventionshown in Figs. 1 to 8 inclusive, and as will be understood in clampingthe parts together for the casting operation the hook ends 27 of theclamps are passed through the recesses 35 in the Webs of the containerand the recesses in these hook ends caused to engage the staple bars 36.The clamp members extend over the sides of the container as well as thesides of the back and front members of the mold and the levers 30 areturned to position to cause the eccentrics to engage the faces ofthebosses on the front member in precisely the same manner as isdescribed in coni'iection with the form of the ii'ivention shown inFigs. 1 to 8 inclusive.
